Application of Embedded QR Code Module

Embedded QR code scanner is a device for scanning and decoding QR codes, it can scan and recognize QR codes like a normal scanning gun. This kind of equipment can usually provide developers with standard serial TTL or RS232, USB interface to meet the needs of embedded design with or without operating system, so it can be easily embedded into other equipment, such as access control gate equipment, automatic Various embedded and integrated applications including self-service equipment such as lockers and self-service vending cabinets.

With the wide application of QR codes in business and daily life, the demand for embedded QR code scanners is also increasing. It can be used to recognize QR codes on paper documents, and can also be used to recognize QR codes on the screen and convert them into digital codes for automatic identification and processing of information. The emergence of this technology enables the information processing of many traditional devices to be completed more quickly and efficiently. In fact, this embedded QR code scanner has been widely used in authentication, ticket management, barcode payment, device control and other fields. From the design point of view, the embedded QR code scanner has the following advantages:

First of all, the embedded QR code scanner is easy to operate and does not need any other equipment during operation. The user only needs to place the QR code to be scanned in the scanning area of the scanner; then, the scanner reads the QR code through the built-in CMOS photosensitive device and a special lens module, and uses the decoding algorithm to decode it; Finally, the scanner sends the decoded data to related devices or systems to realize corresponding functions.

Secondly, the reading accuracy and scanning speed of the embedded QR code scanner are very high. Due to its built-in excellent industrial-grade CMOS imaging technology + intelligent image recognition system, its recognition rate is high and the scanning speed is faster. At the same time, for low-quality barcodes, ultra-dense two-dimensional barcodes, and extremely low-brightness screen codes and other complex two-dimensional codes, the embedded two-dimensional code scanner can also quickly capture the 2d code information.

Once again, the embedded QR code scanner supports multiple working modes, including inductive reading, command trigger, and constant light mode. This greatly expands its scope of application to meet the needs of various users.

In general, the embedded QR code scanner is a functional module built into the terminal device that can read QR codes at high speed. After various debugging and setting of the scanner through configuration tools, it can help users quickly obtain Relevant information, improve work efficiency and convenience, and achieve more accurate and effective code reading and scanning. As the application range of QR codes becomes wider and wider, the demand for embedded QR code scanners will also increase. In the future, we can expect this device to play a more important role in various fields.
